Agree.
Are you talking about those who are in the church becoming more mature in the faith and growing towards sanctification before Jesus returns?
If we're talking about the whole church right now then, yes, it would seem like we're nowhere near being at that point. But, I think what can happen to speed up the process, and what I actually believe has already started to happen, is that those who are mature and growing in the faith can continue to grow and become more Christ-like while others who are not growing, and instead are regressing, end up falling away. And their falling away actually removes some of the spots, wrinkles, blemishes and stains from the church that Ephesians 5:27 is talking about and actually makes the church as a whole closer to the glorious church without spot or wrinkle that Jesus wants to be able to present to the Father.
